By this structure it will be seen that the the controllers at each and. of the car, the

cam-roller at the rear encl of the ca a3? Ways m an ofi pasztmn that the dame-s as sure ts @pem'ce when the cot-atmiier a:

the front of the car is being operated by the motoman, to out the current to the heaters when the controller is moved to the on position suprilying the current to the E motor, and turn on the current to the heaters when the controller is moved to the off position. b In the form shown in Figure 2 of the drawings like reference numerals indicate 19 like parts so far as the controllers and con tacts are concerned, and the operation there of is the same and therefore another .de scription of these parts and operation is not necessary. In this form the wire 6 leads from the switch 5, to the heating system shown through the resistance 18 through the relay switch 19, and through the wire 20,." through the wires 21 and relay 22, and,

. 7 through the fuse 23,- out through the wire 2% at to the thermometer 25, and returning therefrom through the wire 26 and out to the wire 8 and is grounded, through the controllers the same as described in respect to Figure 1. This takes place when the temperature is at or above the desired point.

When the temperature falls below this predetermined point and the controller is turned 0% and the circuit is broken through the thermometer the current is shunted from 30 the relay through the wire 27 to the magnetic coil 28, operating the snap switch 29, and. the current passes directly from the wire 6 through the switch 29, and wire 30, to the heating coils 31-and is grounded.

' When controller is on the on position the cir cult is broken and the snap SWIi/Cll-HDClQI the tension of a spring returns to its normal open position and the heaters are not in operation.

In the form shown in Figure '3 of the drawings, l run a wire 32 from one of the motor leads in the controller box through a resistance coil 33 to the thermometer lead 2 When the controller is on a small cur- 1 rent will flow from the motor lead up through the fuse 23 into the relay 22, and through the resistance 34 to the ground thereby closing the relay switch 19 and, allowing the trolley current from the resistance 18 to flow through the relay switch and wire 35am resistance or to ground. This shuts the current from the magnetic coil 28 causin the switch to open so no current flows trough the wire 30 to :the heaters 31.

When the controller is on the 0% position no ciu rcnt flows through wire 32 and relay switch 19 is open so current from trolley flows through resistance 18, and magnetic .coil 28, though resistance 34 to ground energizing coil 28, and. closing switch allowing current to pass from the trolley through wires 26 and 30 to the heater a l and ground.

Havini thus fully 65 tion what I claim is descrihed my inveneaaees .1. A heating system. comprising a heating coil, and means controlled by the motor controller for cutting off the current from the heating coil when the current is passing to the motor.

2. A. car heating system. comprising a heating coil, and means operated by the motor controller for cutting oh? the current from the heating coil when the current is passing to the motor, and turning on to the heating coil when it is out ofif from the motor. 1

3. A car heating system comprising a heating coil, and means carried by the motor controller for engaging the terminals 39 of an electric heating system. for closing the circuit when the controller is in a position with the current cut 05 from the motor and breaking the circuit when the controller is moved to ease the current to the motor.

5. The combination with an automatically controlled car heatin system, of means operated by the control er for cutting oh the current from the heating" coils when the controller is supplying current to the I motor and turning it on to the heating coil 13 when the current is cut oil from the motor.

6. The combination with an automatically controlled car heating system, oi a circuit opened and closed by the controller for cutting the current "from the heating t coils when the controller is supplying cur.- rent to the motor, and closing the cincuit and completing the second circuit for supplying the heater with current when the controller is in an 0% position. o v
